Nah, that doesn't work either AFAIK: I have kernel: *4.4.68-ti-r110 #1 SMP* I enable pwm as:* bash -c 'echo 1 > /sys/class/pwm/pwmchip4/export'* Then I set ttyO4 tx as: */usr/bin/config-pin P9_13 uart*
and when the app runs it gives me a file not found bleat. Indeed the pwm files are not there. * /usr/bin/config-pin P9_11 uart* is allowed though, so I can read but not write to the tty.
